4400 Elmbank Ave St Louis, MO 63115

ST. LOUIS COUNTY (KMOV.com) – Police have identified the body found in a car Tuesday, to be the mother of a 3-month-old boy found abandoned in a Breckenridge Hills apartment complex.

Authorities say Ebony Jackson, 30, was found dead Tuesday morning after investigators located her car in a north St. Louis neighborhood.

Officers were able to find the vehicle on the 4400 block of Elmbank with the help of a GPS tracking device. These devices are installed in vehicles to allow it to be located if payments are not made.

Police were not sure how long the car had been parked there. But some neighbors say it’s been several days.

The cause of Jackson’s death has not been determined as homicide detectives take over this investigation.

The search started Friday morning when Jackson’s 3-month-old son, Donovan Prom, was found at 5 a.m. at the Hickory Trace apartment complex in Breckenridge Hills. The hallway was fully enclosed so the child was shielded from the cold morning. He was in a car seat, with a blanket over him and a bottle of milk by his side. A resident of the complex found the child as he was going to work and called police.

Local family members came forward after seeing the child’s photo on the news. They told investigators that Jackson lived in Oklahoma City with her boyfriend and the child’s father, Craig Prom, but was coming to East St. Louis to visit. Jackson reportedly saw local family members before she disappeared.

Relatives spent hours Sunday searching for clues around the apartment complex, placing “Missing” posters with Jackson’s photo on trees and walls. Her story was also posted on the website hopeforallmissing.org.

Relatives told police that Jackson had several surgeries on her brain and suffered from impaired memory, even jotting notes to herself so she’ll remember things. The reason for the brain surgeries wasn’t clear.

Heisse said neither Prom nor Jackson had any known connection to the apartment complex. He said there was no video surveillance there, and surveillance cameras at neighboring businesses were not pointed in that direction.

St. Louis homicide detectives are working with Breckenridge police in the investigation.
